Battery powered filaments - the downside being that batteries tend to be large and need charging.
My last foray into battery powered filaments with a car battery ended badly with a trip to A&E, when a certain imbecile removed the charger croc clips from the battery terminals, without switching the charger off from the mains. The resulting spark caused the battery to explode! After a day at A&E where I thought I might lose my sight, I spent the following day pulling up a carpet that was ruined with battery acid and hunting for small pieces of plastic battery casing, 15ft away on the opposite side of the room. Regulated DC supplies are less dangerous, for me at least!
EDIT: A&E == ER (A&E is an abbrev. for Accident and Emergency. Otherwise known as the Emergency Room by our North American friends. Someone just asked me!
)
